| Abstract: |
| In recent years, the exploration of community living circle mode has become an
important task in the construction of major cities. As an important part of community services,
the improvement of the quality of green space in community living circles is not only an
effective way to achieve accurate allocation of public resources, but also a manifestation of
urban spatial fairness and social justice. The 5-minute community life circle is the smallest unit
of community life circle planning, and it is also the most basic unit of urban construction, urban
operation and urban residents’ life. As an important part of public services in the community
life circle, community green space plays a non-negligible role in improving the quality of life
and well-being of residents.
Based on the dual background of 5-minute community life circle and community green
space construction, this study takes 11 community living circle green spaces in Xinxing Street,
Heping District, a typical community in Tianjin as an example, obtains experimental basic
data through objective index quantification and subjective questionnaire evaluation, and uses
factor analysis and entropy weight calculation to determine the main factors and evaluation
indicators. Combined with the grey correlation analysis, a subject-objective green space quality
research model was established, the quality of green space in each community living circle was
evaluated, and the correlation degree of each factor was graded, and then based on the above
analysis, an optimization strategy to improve the quality of green space in living circle was
proposed.
The results are as flollows. Firstly, the green space quality of the 5-minute community
living circle of Xinxing Street, Heping District, Tianjin, from high to low, was Chaoyangli
living circle> Xidi living circle> Weihuali living circle, Xikang Road living circle> Xingheli
living circle> Xinxing Beili living circle> Weijin Road living circle> Jinquanli living circle>
Xinxing Nanli living circle> Tushan Garden community living circle> etc Yongfengli living
circle. Most of the 5-minute community living circle green space quality is generally high,
while Yongfengli living circle and Tushan Garden community living circle are affected by the
community park green space and amusement park green space, the overall green space quality
is poor, and the construction of 5-minute community living circle in Xinxing Street should
focus on improving the quality of community parks and amusement park green space. Secondly,
the factor types can be divided into three categories: activity guarantee, landscape elements and spatial characteristics. Through the analysis of 11 subjective-objective analysis models of 5-minute community life circles, it is found that activity
guarantee and spatial characteristic factors have a greater impact on the quality of 5-minute community life circle green space, and landscape element
factors have little influence on the quality of 5-minute community life circle green space, among which activity guarantee factor is an important
factor affecting the use experience of community residents. The contribution of landscape feature class factor to the quality evaluation of community
park green space was the lowest, and the contribution degree to amusement park green space and residential land attached green space was average.
The spatial characteristic factors have little influence on the main use perception of community park green space, and have a significant impact on the
main use experience of amusement park green space and ancillary green space. Therefore, according to the weight contribution of different indicators,
this paper proposes an optimization strategy for the quality of green space in the 5-minute community living circle from three aspects: activity
guarantee, landscape elements and spatial characteristics, and from the perspective of activity guarantee, measures such as “using shaded space to
increase the ratio of green space activity venue”, “seeing green in the seam to effectively increase the ratio of activity venue”, and “building three dimensional greening to improve the greening rate” are used to improve green space and activity area. From the perspective of landscape elements,
the number of landscape sketches and fitness facilities is increased through “incremental quality improvement of green space fitness facilities” and
“addition and supplement of green space landscape sketches”. From the perspective of spatial characteristics, it is optimized by measures such as
“encouraging the opening of dedicated green space, increasing the per capita area of green space in the living circle”, “creating a community cultural
atmosphere, and strengthening the characteristics of green space space”, so as to improve the theme use evaluation and green space quality of 5-minute
community life green space. |
